Modular paper deformation system with changeable deformation tool drawer

Abstract

To accurately place a modular replaceable or changeable deformation tool drawer (200) in position on a frame frame (1), and permit a variety of different operating procedures to be carried out on printed products supplied to the system without requiring substantial adjustment, the operating tools are retained in a box-like deformation tool drawer which can be inserted in the frame, and held in position by a group of clamping elements, such as fluid operated or electromagnetic cylinders and/or pistons, and, in addition, hold-down screws (6) are secured to the frame to hold the drawer in position on the frame and permit fine adjustment thereof with respect to the frame, and hence with respect to a paper web passing therethrough, before securely clamping the drawer by the clamping elements for production operation.

What is claimed is: 
     
       1. A modular paper deformation system with a changeable box-like deformation tool drawer (200) including a frame (1);   two holding rails (2, 3) having essentially an inverted L shape mounted on said frame, said rails being spaced from each other,   wherein the L-shaped rails define open sides,   said open sides of the L facing each other and defining, therebetween, and together with said frame, an insertion channel (4, 5),   said box-like deformation tool drawer comprising   guide means (19, 20) laterally located on said deformation tool drawer, positionable in said holding rails and engageable in said insertion channel (4, 5);   each of said holding rails comprising at least two clamping means being (11-14) (2, 3) engageable with said guide means (19, 20) on the deformation tool drawer (200) for clamping said tool drawer in position on said holding rails and hence in said frame (1); and   a hold-down means (6) secured to each of said holding rails (2, 3) for holding said deformation tool drawer in position on said holding rails (2, 3) essentially without play when said clamping means (11-14) is released to permit adjustment of the position of said deformation tool drawer with respect to said frame and subsequent clamping of said tool drawer in said adjusted position.   
     
     
       2. The system of claim 1, wherein said clamping means comprises fluid operated clamping cylinders (11-14). 
     
     
       3. The system of claim 2, wherein said fluid cylinders (11-14) are hydraulic cylinders. 
     
     
       4. The system of claim 2, wherein said fluid cylinders (11-14) are pneumatic cylinders. 
     
     
       5. The system of claim 1, wherein said clamping means comprises electromagnetic clamping means. 
     
     
       6. The system of claim 1, wherein said frame (1) further includes two support rails (7, 8) located between the holding rails (2, 3) and positioned essentially parallel with respect thereto; and wherein at least one of said holding rails includes two spaced guide rollers (9, 10) having axes of rotation perpendicular to said support rails.   
     
     
       7. The system of claim 6, wherein only one of said support rails includes said two guide rollers (9, 10). 
     
     
       8. The system of claim 6, wherein said box-like deformation tool drawer (200) comprises an essentially block-shaped body having a bottom (15), two side walls (16, 17) and a back wall (18); said guide means comprises two laterally projecting rails (19, 20), engageable by said clamping means (11-14);   and wherein said-hold-down means (6) are positioned with respect to said guide rails (19, 20) to permit movement of said tool drawer essentially without play over said support rails (7, 8) and permit fine adjustment of said deformation tool drawer prior to clamping by said clamping means (11-14).   
     
     
       9. The system of claim 6, wherein said box-like deformation tool drawer (200) comprises an essentially block-shaped body having a bottom (15), two side walls (16, 17) and a back wall (18); said guide means comprises two laterally projecting rails (19, 20), engageable by said clamping means (11-14);   wherein said hold-down means (6) are positioned with respect to said guide rails (19, 20) to permit movement of said tool drawer essentially without play over said support rails (7, 8) and permit fine adjustment of said deformation tool drawer prior to clamping by said clamping means (11-14),   and wherein said bottom (15) of the deformation tool drawer (200) is formed with at least one guide groove (29) in which said guide rollers (9, 10) are engageable for guiding the position of said tool drawer with respect to said frame during insertion movement of the tool drawer of said frame.   
     
     
       10. The system of claim 1, wherein said hold-down means comprises clamping screws (6) passing through each of said L-shaped holding rails. 
     
     
       11. The system of claim 10, wherein said holding screws include counter nuts for securing said holding rails in position. 
     
     
       12. The system of claim 1, wherein four clamping means are provided, two, each, being located on each of said guide rails (2, 3).
